Shellscripts

This project consists of a set of Shell scripts designed to automate the configuration and installation of a server environment. It covers several essential steps to set up a server with the necessary functionalities. Below, we describe the key features and steps of the project:

Warning: This script is intended for non-production, testing, and development environments only. Using this script in a production environment can pose security risks and is strongly discouraged. Always follow best practices for production server configuration and security.

Key Features:

1. Installation of Essential Packages:

The script begins by installing essential packages to ensure the server has all the necessary dependencies for subsequent steps.

2. Network Configuration:

The next step is network configuration. This involves setting up IP addresses and gateways, ensuring network connectivity is established and configured correctly.

3. Adding Firewall Rules:

To enhance server security, the script adds rules to the firewall. These rules are designed to control inbound and outbound traffic, allowing only necessary connections and blocking unwanted traffic.

4. Installation of Docker and Kubernetes:

The project automates the installation of Docker and Kubernetes. These tools are essential for deploying and managing containers and applications in a server environment.

5. Installation of iptables-persistent:

iptables-persistent is installed to ensure that the firewall rules are persistent and survive server reboots. This is crucial for maintaining firewall consistency and security.

6. Docker Post-Installation:

After Docker installation, the script performs necessary post-installation steps to configure Docker correctly and ensure it is ready for use.

🍍 Problems 🍍

• 3 error messages at the end of the script:
  • bash: ./.bashrc.colors: No such file or directory
  • bash: ./.bashrc.func: No such file or directory
  • bash: ./.bashrc.github: No such file or directory
• Docker post install script is broken
• Network Config. Problem with conditional structure in network configuration. (script.sh file)
• Firewall Config. The problem with the conditional structure of the network configuration, script.sh file, affected the firewall settings. The variables used by the firewall configuration come from the network settings.

📝TODO

• If docker is not installed do not run docker post install script.
• file: configure_firewall
  • Check if firewall rules exist. part of command (example) grep -- "-A FORWARD -j DOCKER-USER"*
  • Check if firewall rules exist. (example) grep -- "-A FORWARD -j DOCKER-USER"
• file: configure_interfaces
  • Add more configuration options in the interfaces file
    • Add options for configuring IP, NETMASK, GATEWAY, BROADCAST... etc
• file: configure_resolv
  • Add more configuration options in the resolv.conf file
    • Add options to add more DNS
